Import Tips

• Verify material composition certification showing brass content to confirm 'other materials' classification excluding iron/steel

• Include documentation proving use in semiconductor manufacturing to support valuation and potential duty relief programs

• Ensure valves meet pressure and leak test standards for cleanroom compatibility to avoid customs holds
